The Sun Hydraulics SCEBLAV (Material Number: SCEBLAV) is an atmospherically referenced, direct-acting sequence valve with a reverse flow check. It is designed to supply a secondary circuit with flow once the pressure at inlet port 1 surpasses the valve setting, while an integral check valve facilitates reverse flow from port 2 to port 1. This sequence valve regulates pressure at port 1 relative to atmospheric vent, making it suitable for load holding applications where a drain connection is not feasible. The design incorporates Sun's floating style construction to minimize internal binding due to excessive installation torque or machining variations. The valve has a capacity of 30 gpm (120 L/min) and operates at a maximum pressure of 5000 psi (350 bar), with a typical response time of 2 ms. It allows for approximately one drop (0.07 cc) of fluid leakage into the vented spring chamber every 4000 cycles. The maximum valve leakage upon reseat is limited to 10 drops/min (0.7 cc/min). The check cracking pressure stands at 25 psi (1.7 bar), and adjustments can be made using an internal hex screw with up to five clockwise turns needed to increase settings. Installation requires specific torques: valve installation torque ranges from 45 - 50 lbf\u00b7ft (61 - 68 Nm), and locknut torque ranges from 80 - 90 lbf\u00b7in (9 - 10 Nm). The model weighs approximately .60 lb (.30 kg) and uses Viton seal kits for maintenance purposes, specifically cartridge Viton: part number 990203006.
